They all trained using an innovation called "Karaoke". They all are of Filipino heritage where every single household in the Philippines and everywhere you see a Filipino in the world has one.
Nowadays its being called Magic Mic where the karaoke machine got compact but it also now holds between 5,000-15,000 English and Tagalog songs in a small package.
The Japanese first marketed the machine they dubbed "Karaoke" in the early 80's but in all reality its a Filipino innovation. Before the advent of CD, everybody in the Philippines uses the old cassette tape deck player to play the instrumental tapes of popular English and Tagalog songs. It was only in 1983 that the Japanese marketed the machine as "Karaoke" and the first country in Asia that it hit was the Philippines.
